AI Technical Summary

Benefits of technology

The patent describes an upper arm for a vehicle suspension that includes a main plate and a subsidiary plate. The main plate has a Y-shaped design with two bush fittings and two walls, and the subsidiary plate has a bottom part and a side part. The main plate and the walls define an open cross-section, while the main plate and the subsidiary plate define a closed cross-section at the second end of the main plate. The technical effect of this design is to provide a more efficient and stable attachment of the upper arm to the vehicle body, while also improving its overall strength and durability.

Problems solved by technology

The upper arm is limited to being mounted on certain components.
For example, a double wishbone type suspension system has very little design freedom.

Embodiment Construction

[0013]A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. A first mounted-bush fitting end 7 is provided at one end of a main plate-shaped member 1, and second and third mounted-bush fitting ends 8 and 9 are provided at the other end thereof. The upper arm is generally Y-shaped, with an opening OA (FIG. 2A) on its underside. A subsidiary plate-shaped member 20 is attached to opening portion OA at second and third mounted-bush fitting ends 8 and 9 of main plate-shaped member 1.

[0014]Subsidiary plate-shaped member 20 closes the side and bottom of second and third mounted-bush fitting ends 8 and 9, and thus forms closed portion CA (FIG. 21B) at second and third mounted-bush fitting ends 8 and 9.

[0015]A body part 2 of main plate-shaped member 1 is generally Y-shaped. Further, left and right side parts 3 and 4 of the main plate-shaped member 1 close off the sides of body part 2, so that opening portion OA is forme...

Abstract

An upper arm for a vehicle suspension includes a main plate and a subsidiary plate. The main plate includes a first bush fitting at a first end of the main plate, configured to be attached to a wheel knuckle; second and third bush fittings, spaced apart from each other at a second end of the main plate and configured to be attached to a vehicle body; and two walls at first and second sides of the main plate. The main plate and the walls define an open cross-section along a substantial portion of the main plate. The subsidiary plate is attached to the second end of the main plate. The main plate, the walls, and the subsidiary plate define a closed cross-section at the second end of the main plate.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is based on, and claims priority from, Korean Application Serial Number 10-2007-0104516, filed on Oct. 17, 2007, the disclosure of which is hereby incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a double plate type upper arm for a vehicle suspension.BACKGROUND OF THE INVENTION[0003]A suspension system prevents a vehicle from joggling caused by irregularities of the road, and adjusts vehicle height or damping force based on running conditions, such as road conditions and vehicle speed.[0004]A suspension system generally includes springs, shock absorbers, stabilizers, and a pair of arms, one lower and one upper, attached between the vehicle body and the wheels. The suspension system mainly functions to adjust a spring constant, a damping force, and the vehicle height. Further, the suspension system functions to improve the ride comport and stability of a v...
